Just tested compat-wireless and yes it works! Here the TX info struct takes exactly 48 bytes so it can fit well into the control buffer. Btw, I came up with the 'iwlagn: Unknown symbol iwl4965_agn_cfg' issue though (actually also in compat-wireless-old). Strange as it seems there're already some treatments there. Will look at it later. While it's great to see compat-wireless working for more old kernels, I wonder if compat-wireless-old is still actively maintained? Asking this because currently most of the documentations still describe it as 'compat-wireless-old for <= 2.6.26 and compat-wireless for >= 2.6.27', and I was probably not the only amd64 user reading that. :) Best regards, Gao Lei -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
